Curve :

Archimedean spiral



It has many uses. It can be intriguing.


Proof :

Lune of Hippocrates, named after Hippocrates of Chios :




Hippocrates of Chios wanted to solve the "quadrature" of the circle but solved the lune instead.

Euclid, Aristotle and many other mathematicians liked the proof a lot.


Formula :

Eddington number.



The Sand Reckoner (Ψαμμίτης / Psammites) is a work by Archimedes in which he set out to determine an upper bound for the number of grains of sand that fit into the universe. In order to do this, he had to estimate the size of the universe according to the contemporary model, and invent a way to talk about extremely large numbers. The work, also known in Latin as Archimedis Syracusani Arenarius & Dimensio Circuli, which is about 8 pages long in translation, is addressed to the Syracusan king Gelo II (son of Hiero II), and is probably the most accessible work of Archimedes; in some sense, it is the first research-expository paper.[1]


Arhimedes and Eddington were both right ! :)




As proof, I also like the one measuring the craters in the moon.

Curve: y = (x+1)/(x-1) (Not named for all I know)

That's all I really care. Infinity is just a concept, and this line goes up that far.

My favorite curve is the female Ass.

In regards to thread, i don't like math beyond algebra. I don't know how I'd ever use it. If i can't do the math in my head, it's a math i deem negligible. In that same aspect, i know some people appreciate maths to this extent and i can respect that.

That said, i do like this formula :
The quadratic

X = -b +/- (sq. Root thing) b (squared) - 4 (a)(c), all of that divided by 2a.

um ^2 is squared Genghis.

I like 1+1=2 because it is always right... or does it equal a window... or 11...

Genghis, you beat me to putting quadratic formula.

Also, I do agree. Most people will not use the math they learn in school.


teach teens to operate a cash register, or a really old computer (as most computers in stores haven't been updated)- it will help a lot more.

I can do algebra, geometry, and trigonometry in my head. My favorite curve is X^5 because it has the highest "quintuplet" formula. They can't make a formula like the quadratic formula for X^6.

My favorite proof is the one that pi is a constant.

my favorite formula is

d
dx e^u=u'e^u

because it doesn't change if u=x.

Formula is : F(2x²)³+F(y-x²)²
All values can be infinity or an absolute value it does not change with both.

Other favorite's

C(pi³)=V²+A
C can have infinity it still works

Curve: A parabola, just cos they are sexy. Also maybe an exponential curve, because they are cool.

Proof: I don't really know any proofs, but then I'm not a mathsmatician.

Equation: E=MC^2 because it is so sexy, and it's held true even over such a long time of scrutiny.

Edit: I also like Euler's equation: e^(i*pi) = -1 because it just blows my mind that two irrational numbers and an imaginary one can equal -1!

If I can add to this list:

Number, that would be Avogadro's number because it so beautifully ties in matter to weight. (It's used a lot in chemistry.)

And constant: Planck's constant. Because it's the smallest number that makes any sense! :D
